Avoids a bogus "argument unused" warning, since bitcode compilation doesn't bother to set up much of a Clang AST context. (-embed-bitcode compiles in two steps: source -> bitcode, then bitcode -> object file. This is about the second step.) Patch by Bob Wilson, who's currently on vacation but wanted this to get in sooner rather than later. rdar://problem/31372950
